Previously, the company announced a three-year, $6 billion share repurchase authorization, effective January 1, 2026. This capital return plan reflects management’s confidence in the company’s long-term value creation.
How Do AI Data Centers and Silicon Carbide Form a Dual Growth Engine?
ON Semiconductor’s core growth narrative currently centers on two themes: AI power management and silicon carbide (SiC) technology.
In the AI data center space, the company is experiencing an "inflection point" in demand. In Q1 2026, AI data center revenue grew over 30% quarter-over-quarter and more than doubled year-over-year. Management now expects full-year 2026 AI data center revenue to double compared to the previous year. This growth is fueled by the widespread adoption of efficient power conversion and management solutions by hyperscale cloud providers and GPU/CPU platforms. The company projects that the power semiconductor content per AI server rack will soar from the current $15,000 to over $110,000.
ON’s product portfolio covers the entire AI power chain—from the grid to processors inside data centers—including silicon carbide, gallium nitride, intelligent power modules, and mixed-signal technologies. This breadth positions ON advantageously to capture the wave of AI infrastructure investment.
In silicon carbide, ON’s EliteSiC technology is a key driver of next-generation electric vehicle (EV) architecture upgrades. The company revealed that nearly 55% of new EV models showcased at the 2026 Beijing Auto Show use its silicon carbide technology. ON is working closely with major Chinese automakers such as Geely and NIO, supporting next-generation 900V EV platforms. The 900V architecture enables faster charging and longer range, with silicon carbide devices serving as the critical enabling technology. ON’s long-term partnership with NIO now extends to the next-gen 900V platform, including its latest flagship SUV, the ES9.
Why Is ON’s Breakthrough in China’s EV Market Strategically Significant?
China is the world’s largest EV market, and its technical standards are increasingly shaping the global industry. ON’s performance in China is noteworthy: despite overall weakness in China’s passenger car market in Q1 2026, ON’s automotive revenue in China still achieved year-over-year growth. This "countertrend growth" indicates that the company is capturing higher content per vehicle and expanding market share.
Management points out that Chinese automakers are driving a shift toward higher-efficiency vehicle architectures, creating long-term structural demand for ON’s power semiconductors. As China’s EV exports continue to rise, ON’s market opportunities are expanding from the domestic market to a global scale. The ongoing trends of regional vehicle electrification and intelligent driving are expected to further strengthen ON’s market position in automotive power semiconductors.
It’s also worth noting that ON recently announced a reduction of about 200 to 300 employees in its silicon carbide wafer manufacturing division in Rožnov, Czech Republic. This decision comes as Chinese silicon carbide suppliers, supported by government subsidies and low electricity costs, have reduced wafer production costs to about one-third of those of their Western peers. This development highlights the cost pressures ON faces in silicon carbide and signals that the company is proactively adjusting its capacity footprint to respond to market changes.
